Economy
Compared with incandescent lamps of similar luminous flux, OSRAM DULUX
consume only one quarter to one fifth of the electrical energy.
OSRAM DULUX
remain switched on for long periods. The following table shows the clear cost savings:

To this figure must be added the savings in relamping costs. An OSRAM DULUX
used with conventional control gear will last around eight times as long as an incan-
descent lamp, and around ten times as long if it is operated with electronic control
gear. The extra cost of purchasing an OSRAM DULUX
electricity costs after as little as 1000 hours of operation, depending on the wattage.
Cost/benefit analyses can also be carried out with the OSRAM ECOS program (see
OSRAM Lighting Programme on CD-ROM).
